I installed the voltage regulator, and the sound on my hifi is much better now, computer kept crashin though, I don't know why but I imagined the problem would be too low voltage, but the indicator on the regulator says that I am getting too high voltage ( not always I saw it go on a couple of times). anyway, after a lot of work and fiddling around, it turns out it's a problem with quad core cpus and the motherboard I am using ( cheap motherboard ASRock 4corequad-sata2), all I had to do to get it to run without crashing was change a value in the bios. I just got me a new motherboard today, will install it tonight, and install 64bit intrepid. Thanks for your support!

From what I understand, AMD have only recently (in the past couple of months) released technical documentation from which drivers can be made so unless you go for an oldish card you're probably going to find patchy support, but the thing is, eventually it'll get better. My Radeon X300 card has fairly reasonable support but my Radeon All-In-Wonder X800 has pretty lousy support (none of the All In Wonder features work at all, saying that, they don't work on Vista either :-) Rob -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hello, The rams are not the cause of the freeze, as it froze with each of them separately. Rob, I dont know why, for some reason I assumed that there is no warranty on the thing, I contacted the seller, my warranty runs out in november! and he told me I can either send the whole pc to him, or just the motherboard and cpu if I am sure it's one of them that is faulty (which I will be after testing the PSU). so at least I know I won't be paying for a new cpu or motherboard if they are broken. Ian, I am borrowing the PSU from a friend (and finally i have it in hand), not buying until I know that it's the problem. thanks for mentioning the protection, I have ordered one today, APC Line-R 600VA Line Conditioner, even if it's not the cause of the problem it's a good thing to have, will connect my hifi to it as well, should be good! Will install PSU today, and see if there are any changes. As I mentioned earlier, I was annoyed by how loud my GPU fan is, and decided to go for a passively cooled one. I got an ATI because as i recall AMD have opened their drivers and I thought they are working great. I can't get Xv to work on the video card, there are some reports of success on the net, but I've had enough fiddling around, I'll return it and just buy a vga cooler for my nvidia card. but AMD should be ashamed that they still haven't sorted out their drivers!

Re: [ubuntu-uk] Hardware failure?
Hi Seif Before going down the new PSU route, do you have any power conditioners on the mains supply to your box? If not, that would certainly be the next purchase I'd recommend, followed by the PSU afterwards. To my inexperienced eyes, if a full power off and break with mains is required to reset things, it certainly does point towards the PSU, but it could still be spikes coming in over the mains and causing the PSU to wobble. In which case, even with a new PSU you'd still be liable to wobbles, but maybe not as dramatic as you get currently.

My suspicion would be on overheating and memory. Open up the case and ensure all components are firmly seated down. Then use a vaccuum cleaner to suck out all the dust, particularly from the heat sinks. Then try running the machine with the case open, and check to see that all the fans are spinning. Second, if you have two memory modules, pull one out and try running with the remaining one on its own. Then shut down, swap over the modules and run again. If it runs with one but not the other, you now know which is faulty. Finally see if you can swap the CPU and graphics card out for another (friend's?) known-good CPU & GPU. If that doesn't crash, you know your CPU or GPU is faulty; test each in turn.

I had a problem with my machine a while ago to do with the onboard SATA controller. I had semi frequent crashes (in both win & lin), and after a month or two of this the hard drive would give up.

If, as you say, it's built from the cheapest possible parts then it's very likely that they've used a no-name "high wattage" power supply which are known for causing problems. A quad core processor and 8800gt gfx card aren't going to be low power either. Even if the new graphics card is lower power and the problem goes away I'd still replace the power supply as cheapo ones aren't known for their reliability and have been known to damage other components when they fail.

On the subject of hard drives - it could well be a dodgy hard drive, particularly if it's a cheap one, try using a live CD for a while - it'd be the easiest way to test without fiddling with hardware, if that works fine, It'll very probably be the hard drive, and it'll need replacing. > > > Do you know if the HD is SATA or IDE?

I had a similar problem, random lockups, system totally non-responsive, reset the only way to get the system back up. I tried swapping out all my hardware with no solution until I install the system onto an old IDE drive I had, the SATA drive was fine, in fact my system runs on it now so I figured it might have been a chipset driver issue (or not?) Either way changing from a SATA drive to an IDE drive solved it for me.

The symptoms have changed since it first started. before it used to freeze, no mouse moving, no keyboard, sysrq doesnt work, but display showing last app running on X, and nothing in the logs,then I noticed that if I have some apps open when the crash happens (e.g. mythtv) i do get something in the logs, see attached file with different data from different days, logs dont always get written to, these messages keep repeating in the logs. I don't know if any1 can make anything of those things. but the freezes are completely random! they happen while i am working on the machine, or if i come back after leaving it for a few hours, no matter what apps are running. seriously frustrating. I had checked the temperatures at some point, dont remember what it was, but after googling i found it's normal for a stock fan (somewhere in the 50s), no dust on the fans, all hardware well attached. getting a new video card tomorrow, as the fan on the one i have is quite noisy, and that throws one of the suspects away! any helps would be appreciated. thanks, Seif A.

Have you been inside the machine to make sure all hardware is correctly inserted and seated? The next thing is to check if a specific app is normally running when the machine freezes or give us as best description of what happens i.e. After a long time running, can you dump back to failsafe terminal out of X, is the mouse still working after freeze etc. Be descriptive! :-) Regards Phil signature.asc Description: This is a digitally signed message part -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

Just thinking if it's more than a few months old it might have got a bit clogged up with dust inside. That's worth checking, as you mention, removing the ram is a good idea. Does it free quickly or is it after an extended amount of time? Also make sure the things like CPU fans and any fans on the video card are working okay. You might be able to get the CPU and case temperatures from your BIOS, if so how high is it immediately after a freeze? (It shouldn't go down by much if you reboot it straight after a freeze).
